System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

NokiaTool: control MediaTek-based Nokia phones from your PC

Overview

NokiaTool is a simple Bash script (nokiatool.sh) that allows you to use an undocumented serial connection in USB-enabled MediaTek-based Nokia feature phones manufactured by Microsoft (even the most basic ones, like the new 105) in order to control them from your PC.

This project is an ongoing work and uses only some bits and pieces of information about the phone internals available to the public, so under any circumstances don't consider it stable or a replacement for official tools if any are present.
